JAVA 인앱 결제 ( IOS 구매 내역 호출 )

 

정기 결제를 개발하며 IOS 구매 내역 확인을 해야 합니다.

 

구성

JAVA 8

Spring boot

Maven

코드 먼저 작성 하고 설명하겠습니다.

    Map<String, Object> headers = new HashMap<>();
    headers.put("alg", "ES256");
    headers.put("kid", "TTP2RC247M");
    headers.put("typ", "JWT");

    Date issuedAt = Date.from(Instant.now());
    Date expiredAt = Date.from(Instant.now().plus(Duration.ofMinutes(10L)));
	// 키파일
    PrivateKey privateKey = getPrivateKey("key/AuthKey_TTP2RC247M.p8", "EC");

    String jws = Jwts.builder()

    Map<String, Object> returnList = new HashMap<>();

     URL url = new URL(
            "https://api.storekit.itunes.apple.com/inApps/v1/history/고객구매번호?productId=상품번호&sort=DESCENDING"
    );

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestProperty("Authorization", "Bearer " + jws);
    conn.setRequestProperty("Content-type", "application/json");
    conn.setRequestMethod("GET");

    try(BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()))) {
        String output;
        StringBuffer sb = new StringBuffer();
        while ((output = in.readLine()) != null) {
            sb.append(output).append("\n");
        }

        if (!sb.equals("")) {
            returnList = new ObjectMapper().readValue(sb.toString(), new TypeReference<Map<String, Object>>(){});
        }

    }

    List<String> signedTransactions =  new ObjectMapper().convertValue(returnList.get("signedTransactions"), new TypeReference<List<String>>() {});

    for(String st : signedTransactions){
        String[] check = st.split("\\.");
            Base64.Decoder decoder = Base64.getDecoder();
            String payload = new String(decoder.decode(check[1]));
            log.info("payload :: "+payload);
    }

 

url 은 운영, 개발(샌드박스) 이 있습니다.

저는 운영으로 진행하였습니다. 

sort DESCENDING 진행 하였습니다.

 public PrivateKey getPrivateKey(String filename, String algorithm) throws IOException {
    ClassPathResource resource = new ClassPathResource(filename);
    String content;
    InputStream inputStream = resource.getInputStream();
    try (BufferedReader reader = new BufferedReader(
            new InputStreamReader(inputStream) )) {
        content = reader.lines().collect(Collectors.joining("\n"));
    }

    try {
        String privateKey = content.replace("-----BEGIN PRIVATE KEY-----", "")
                .replace("-----END PRIVATE KEY-----", "")
                .replaceAll("\\s+", "");

        KeyFactory kf = KeyFactory.getInstance(algorithm);
        return kf.generatePrivate(new PKCS8EncodedKeySpec(Base64.getDecoder().decode(privateKey)));
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException("Java did not support the algorithm:" + algorithm, e);
    } catch (InvalidKeySpecException e) {
        throw new RuntimeException("Invalid key format");
    }
}

 

위와 같이 하면 나오는 로그 json

{
    "transactionId":"고객주문번호",
    "originalTransactionId":"고객주문번호",
    "webOrderLineItemId":"주문품목ID",
    "bundleId":"패키지명",
    "productId":"상품명",
    "subscriptionGroupIdentifier":"21419068",
    "purchaseDate":1714782833000,
    "originalPurchaseDate":1714782834000,
    "expiresDate":1717461233000,
    "quantity":1,
    "type":"Auto-Renewable Subscription",
    "inAppOwnershipType":"PURCHASED",
    "signedDate":1718589613537, // 결제 날자
    "offerType":1,
    "environment":"Production",
    "transactionReason":"PURCHASE",
    "storefront":"KOR",
    "storefrontId":"매장아이디",
    "price":0,
    "currency":"KRW",
    "offerDiscountType":"FREE_TRIAL" // 무료체험
}

 

 

inAppOwnershipType  : 구매 갱신 확인

expiresDate                 : 만료 날짜
signedDate                  : 결제 날짜

 

위 데이터로 결제 확인 합니다.
